Prosthetic device with protrusions for girth

Abstract

A prosthetic device comprises a column formed of resilient material. The column comprises external protrusions that vary a girth of the column. The protrusions are separated by valleys that reduce bulk.

1. A penile prosthetic device, comprising:
 a column formed of resilient material and having external protrusions that vary girth, wherein the protrusions are separated by valleys that reduce bulk and are presented in a floret configuration around a diameter of the column. 
 
     
     
       2. The prosthetic device of  claim 1  and further comprising a malleable core arranged inside the column. 
     
     
       3. The prosthetic device of  claim 2 , wherein the protrusions are presented around a diameter and along a length of the column. 
     
     
       4. The prosthetic device of  claim 2 , further including a sheath about the column. 
     
     
       5. The prosthetic device of  claim 4 , wherein said sheath is removable. 
     
     
       6. The prosthetic device of  claim 1 , wherein the valleys define grooves that extend along a length of the column. 
     
     
       7. The prosthetic device of  claim 6 , wherein the grooves are twisted about a major axis of the column. 
     
     
       8. A penile prosthetic deice comprising:
 a column formed of resilient material having an external surface and a major axis; 
 a plurality of protrusions around the column protruding in a radial direction relative to the major axis, wherein the plurality of protrusions displaced from each other along the major axis; and 
 a sheath covering the column and the plurality of protrusions, wherein the sheath comprises corrugations extending around the column. 
 
     
     
       9. The device of  claim 8 , further comprising a malleable core arranged inside the column. 
     
     
       10. The device of  claim 9 , wherein the malleable core has a generally cylindrical external surface. 
     
     
       11. The device of  claim 8 , wherein the protrusions are arranged in a floret configuration around a diameter of the column. 
     
     
       12. A penile prosthetic device comprising:
 a column formed of resilient material having an external surface and a major axis; 
 a plurality of protrusions around the column protruding in a radial direction relative to the major axis, wherein the plurality of protrusions define grooves between adjacent protrusions that extend parallel to the major axis. 
 
     
     
       13. The device of  claim 12 , further comprising a cylindrical malleable core arranged inside the column. 
     
     
       14. The device of  claim 13 , wherein the malleable core is coaxial with the major axis. 
     
     
       15. The device of  claim 12 , further comprising a sheath covering the column and the plurality of protrusions. 
     
     
       16. The device of  claim 15 , wherein the sheath comprises corrugations extending around the column.
